An approach I find interesting is the [Perkeep](https://perkeep.org/) or Google Drive model for post hierarchy.
Storing all files as objects and then indexing..
An interesting indexer for images would be one that groups objects by faces recognized or exif data(camera model, GPS location, lens, date, etc) Google Drive does this.
Perkeep can deal with tags, span devices, deal with permissions. Check out HN user @bradfitz
My main issue with Perkeep is that a lot of the automated tags are very limited, and adding more is not really easy-to-do. Though the last time I used it, it was known as Camlistore. So maybe things have changed (there were some pretty bad UI issues back then as well).
I do like the idea that nothing is deleted and everything is stored using "permanodes" and signatures of objects defining mutations of a "permanode". The downside is that everything is so incredibly dependent on the indexer, and my experience is that if the indexer has a bug you are in a lot of trouble. Also sometimes you don't want to keep everything you made 10 years ago around -- especially if it's burning storage space that costs you money.
